Auxiliary Cohorts and their titles

[Praefectusclassis]

One diploma, iirc. There's a Speidel article with evidence for a II and III Classica, possibly raised from fleet troops during the Jewish revolt of the 130s. The fleets were certainly depleted during that war, likely used to replenish legionary units. There's a remarkable drop in fleet discharge certificates after the revolt, which only pics up after 160, indicating a recruitment drive right after the revolt.
